How many people are there on the earth?

According to statistics in recent years, there are about 8 billion people on the earth.

This number sounds surprising, especially when we go out to play on holidays. Looking around, there are people everywhere, and the earth is almost surrounded by human beings. However, if all the people on the earth are put together, the total area where 8 billion people stand together is only 158 square kilometers. In Europe, there is a small country called Liechtenstein. The total territorial area of this country is 160.5 square kilometers. In other words, such a small country can hold all the people on the earth.

After the industrial revolution, the population on the earth began to grow rapidly. 1850, the world population is 125 billion. 100 years later, by 1950, the world population has doubled, reaching 2.5 billion. Entering 2 1 century, the world population has reached 80 billion. Today, the world population is still growing rapidly, with about 360,000 people being born every day and about 6,543.8+0.5 million people dying every day. In a word, the population on the earth in the future will far exceed the current total population.
